Love the C.S.Lewis quotage , but then he was referring to a still early 20th century, still *Empire-minded*, United Kingdom, England ; the same creeping oppressive "socialism is the future" agendaed government that gave George Orwell his muse that resulted in "1984", was in the afterglow of H.G.Wells' "History" and Algous Huxley , produced Ayn Rand ,and about 14 years later , gave rise to Anthony Burgess' " A Clockwork Orange".I take a back seat to no one when it comes to watching Big Gov't like a hawk , but to even suggest that the market-libetarian agenda of "least gov't is best gov't " which evangelize that there is no , and never was, such a thing "as" a robber baron; only free-enterprising entreprenuers in the Ayn Rand mold , is *grossly* wide of the mark.
I found C.S.Lewis' quote; "The robber-baron's cruelty may at some point be satiated...." especially naive at best and the worst kind of distortive hyperbole employed to make one's point.
I'll offer a counter-quote from another distinguished and uniquely qualitfied representative of the UK's men of letters; Winne the Churchill. You must know the quote; something about "Democratic Gov't is the worst kind of gov't.......except for ALL the others ".
BTW : The minor annoynance of the 3rd Reich that ol' Winnie was concerned with would not have had a chance without the willing embrace of "robber barons" and captains of industry producing the "economic miracle" of New Germany 's "National Socialism" during the global depression 30's.
I know criticizing the Gov't is the great American passtime , and even part of our nature, but some balance is healthy.
